Toy hydrogen rocket launcher.
This plastic globe contains a pair of electrodes and an igniter coil. Normally there would be a lightweight rocket slipped over a tube coming out the top, and it would be mounted in a base filled with batteries. The batteries supply power to the electrodes to split water in the globe into hydrogen and oxygen, and after enough of that has built up, you push the launch button and the igniter coil heats up and lights the hydrogen-oxygen mixture. It goes bang, the rocket shoots up, and glee ensues.Source:Radio ShackContributor:Theodore GrayAcquired:15 April, 2009Text Updated:15 April, 2009Price: $10Size: 6"Purity: 0%
